The ecosystem in between the Larsen Ice Shelf and a giant iceberg is due to be studied:

Scientists will set out in the next week to study an Antarctic realm that has been hidden for thousands of years.

A British Antarctic Survey-led team will explore the seabed ecosystem exposed when a giant iceberg broke away from the Antarctic Peninsula in 2017.

The organisation has also released the first video of the berg, which covers almost 6,000 sq km.

[...] British Antarctic Survey marine biologist Dr Katrin Linse, who is leading the mission, said that the calving of the iceberg, which has been named A68, provides researchers with "a unique opportunity to study marine life as it responds to a dramatic environmental change". "It's important we get there quickly before the undersea environment changes as sunlight enters the water and new species begin to colonise," she explained, adding that the mission was "very exciting".
